I think that in this country --The one that give money to everybody arround the world-- With the perfect economy, cannot produce a vehicle with a diesel engine with low emision.
Mercedes have one that you can pis in it. The problem is money, tax money, The fuel industry support the goverment of the USA by paying a lot of taxes and they (The goverment) will not going to let the cars company to produce a vehicle that will be large, strong and capable of giving 60 mpg. What they will let them to produce are those fagget cars with 40 mpg at the must.
Revenue, money, gentlemen. and that is the issue.
South America, India, Europe, can drive what ever they want what ever the world produce, if you have the money to buy it. But here, you know "IS THE BEST COUNTRY IN THE WORLD".
